Hi everyone. I'm a beginner when it comes to painting and kitbashing Transformers. I've got an airbrush recently, and I've been pracitcing on it (using figures I'm not too fond of) but I haven't really achieved the best results.

Also a friend of mine who works and paints plastics suggested I get thinner for my airbrush, but if I'm using acryllic paints (its all I can find around here in the colors I like) would I still need it? IRC acryllics are water-based paints.

Could anyone be kind enough to give me a few words of wisdom? Thanks in advance :]
